A rate control scheme for distributed high performance video encoding in cloud

There are demands for uninterrupted delivery of increasingly higher quality videos over the Internet from users, while video transcoding stage is a long time and resources consume processing. Cloud computing offers the power to supply on-demand resources dynamically. In this paper, we proposed a video encoding infrastructure and a rate control scheme to improve the coding efficiency on cloud environments. Experimental results demonstrate that our video encoding infrastructure and rate control scheme gains better visual quality.
